What are bronzes?

Bronzes are copper-based alloys, typically with additions of tin, aluminium or silicon. The most traditional bronze is a simple alloy of copper and tin.

There are also families of manganese bronzes, phosphor bronzes, nickel aluminium bronzes (NAB) and aluminium bronzes, each featuring the named metal as the main alloying addition to copper.

Our range of copper-nickel alloys, such as Hiduron^® 130 (DTD900/4805, 2.1504) and Hiduron^® 191 (DEFSTAN 02-835, NES 835), is often referred to as bronzes, although here the main addition to copper is nickel.

Frequently asked questions

What are bronzes made of?

Bronzes are copper-based alloys, typically with additions of tin, aluminium or silicon. The most traditional bronze is a simple alloy of copper and tin, but several distinct families exist, including manganese bronzes, phosphor bronzes, nickel aluminium bronzes (NAB) and aluminium bronzes, each named for its main alloying addition to copper.

Are Langley Alloys' copper-nickel alloys the same as bronzes?

Not strictly, but they are often referred to as bronzes. Langley Alloys' range of copper-nickel alloys, such as Hiduron 130 (DTD900/4805, 2.1504) and Hiduron 191 (DEFSTAN 02-835, NES 835), has nickel rather than tin, aluminium or silicon as the main addition to copper, unlike a traditional bronze family.

What is the difference between a bronze and a brass?

Bronzes are copper alloys typically alloyed with tin, aluminium or silicon, while brasses are copper alloys alloyed mainly with zinc. Bronze families such as nickel aluminium bronze and aluminium bronze are generally used in more demanding applications than brass, which is chosen mainly for its formability and decorative appearance.
